NORTHAMPTON, Mass. (WWLP) – As heavy rain moves into western Massachusetts on Tuesday, the National Weather Service has issued a Flood Warning for the Connecticut River in Northampton, Montague, and just over the state line in Thompsonville, Connecticut.
The warning, which takes effect Wednesday morning, is being issued because much of the river is near flood stage, and is expected to go over flood stage following the rains overnight, combined with the continued melting of snow to our north.
As of noontime, the National Weather Service reports the Connecticut River in Northampton near the Oxbow was at 111.3 feet. Flood stage is 112.0 feet, and the river is expected to rise up to 115.6 feet by Wednesday morning. Flooding is also expected at the Oxbow itself, and along Route 5, which may become impassable.
Additional flooding is possible in low-lying areas of Hadley and Easthampton.
The NWS also predicts flooding along the Mill River in Hadley, causing flooding along Valley Street and surrounding areas.

In Thompsonville, the river was at 4.6 feet as of noon Tuesday, just short of flood stage at 5.0 feet. It is expected to rise to near 6.8 feet by Wednesday morning, just short of the 7′ mark which could result in more widespread flooding in places like Agawam, Longmeadow, Suffield, and Enfield.
The Connecticut River is also expected to go over flood stage farther upstream at Montague, where the river level was measured at 25.9 feet Tuesday afternoon. By Wednesday morning, that is expected to rise to flood stage of 28 feet, and rise as high as 30 feet by Thursday morning, before coming back down. Low-lying areas of Greenfield and Montague that are not protected by levees could be at risk, the NWS says.
